The best church service I've been in did not look like a church service at all. The guy who lead the worship had a voice like liquid velvet. There were no announcements to break up the worship. No preachers in the pulpit. Each person who was lead spoke a verse or two, or a thought or two while the music was played quietly in the back ground. Most were quiet, or quietly ministering to one or two others. There was no looking at watches, no timeframe. No big movie projector or power points (which are beneficial, but for teaching workshops not worship services). It didn't matter at the time if the words to the song were known or could be seen by all. The spirit of the Lord was almost palpable. There were very few dry eyes at the end of that evening.
Have not had congregational worship like that since, but have had that experience many times at home one on one with the Lord.
